Consider the shown Cantilever beam and loading with the Given info.

I $-$ Without drawing the V$-$M diagrams, obtain Vmax. and Mmax.,

$S_Y=42,000$

$E=9\mathrm{.}8{10}^6$

$L=6\mathrm{.}00ft.,$

II $-$ Calculate the Maximum Shear Stress and Plot the "Distribution of Stress"

$F_1=400$Ilb

$($on the next page$)$

III$-$ Calculate the Maximum Bending Stress

IV$-$ What is the Factor of Safety of the Beam?

$V-$ If the beam is turned $90$ and oriented on its weak direction, what would

be the new Factor of Safety?

$F_2=600Il$

$w=40l\frac{b}{f}t$

$B=4^{\text{'}\text{'}}$

$b={3\mathrm{.}5}^{\text{'}\text{'}}$

$H=7^{\text{'}\text{'}}$

$h={6\mathrm{.}5}^{\text{'}\text{'}}$

$t=$ Uniform
